With the technological development of the battery, LiFePO4 batteries are a commonly used type of rechargeable battery, LiFePO4 battery packs provide a more energy-dense and energy-efficient battery chemistry over the traditional lead-acid batteries.The popularity of the LiFePO4 battery is due to the advantages offered over other secondary (or rechargeable) batteries:Lighter than other rechargeable batteries for a given capacity；Li-ion chemistry delivers a high open-circuit voltage；Low self-discharge rate (about 1.5% per month)；Do not suffer from battery memory effect Environmental benefits: rechargeable and reduced toxic landfill.

Traditional Lead-acid Battery vs LiFePO4 Battery

Higher efficiency & more power
Lasts longer with less downtime
Less costs in all service life
The battery can stay on board for fast recharging
No maintenance, watering, or swapping any more
Shipping Cost: LiFePo4 battery can 50% shipping cost
Cycles: 300 VS 2006
The same capacity, the lithium iron phasphate battery has a longer life span of more than 7-8 years
Lead-acid batteries are only 2-3 years old, and iron-Uthium batteries are green, non-toxic and pollution-free

Features Of BMS:

Built-in 32-bit ARM MCU Control Unit.
Provides 2 Ways of Temperature Dectect Sensor (ForCell &BMS Mosfect).
Discharge over current, short circuit protection functional processes of hardware.
Over voltage, under voltage, temperature and overload protection function processing of software.
Accurate SOC calculation with automatic SOC learning function.
With the auto-balancing function, improving the average charging efficiency and the cycle life of the battery in the long term.
